Actually these numbers are related to the block size of a ext4 volume.
To be more specific, with the above number, we have
first_block + block_len > EXT4_BLOCKS_PER_GROUP while
block_len < EXT4_BLOCKS_PER_GROUP.
So do you think it is generic enough for a test case in xfstests since
now this
tool kit is also used to test xfs and btrfs?

xfstests also allows filesystem-specific tests. Most of the specific
tests are for xfs, but there are few for udf right now as well.
